Why do you keep harping on about this 4WD/AWD stuff? Your beloved Alpine Resorts Regulations that you've posted on here and have had considerable input and influence in regarding chains has this definition,
"Division 2—Wheel chains in alpine resorts
23 Definitions in this Division
In this Division— 4 wheel drive vehicle includes an all-wheel drive vehicle"
End of argument.....unfortunately some RMBs continue to make different directives for AWDs in direct contravention of the definition in the regulations under which they operate.
